Answer:
Please see explanation for the answer. The code is written in python and is as given below:
Step-by-step explanation:
The solution is obtained on the Python with the following code
import matplotlib.pyplot as plotter
import numpy as npy
x_s = npy.linspace(-5,5,100) #Defining a linear sample space with boundaries as -5 to 5 and 100 as number of samples.
def sigmo(z):return 1/(1 + npy.exp(-z)) #Defining sigmoid function for the f(x).
plotter.plot(x_s, sigmo(x_s))
plotter.plot([-5,5],[.5,.5])
plotter.xlabel("z")
plotter.ylabel("sigmoid(z)")
plotter.show()
The different combinations is 9, since we can't rearrange the two novels.
I did 3*3 which equals 9.
Answer:
Curved parenthesis at negative infinity
Square bracket at -4
====================================================
Work Shown:
The last inequality shown above is the same as saying
Converting this to interval notation leads to the final answer of
Note the use of a square bracket at -4 to include this endpoint. We can never include either infinity, so we always use a parenthesis for either infinity.
Answer:
Net Proceeds = Selling Price - Total Cost Price
a. Samantha
Total Cost Price;
Bought shares for d dollars and paid 2% commission = d + (d * 2%) = 1.02d
Selling Price;
Sold stock for s dollars and paid flat fee of $11 = s - 11
Net Proceeds = (s - 11) - 1.02d
b. Alex
Total Cost Price;
Bought x dollars worth and paid 1% commission = x + (x * 1%) = 1.01 * x = 1.01x
Selling Price;
Value falls to y and Alex pays 1.25% when he sells = y - (y * 1.25%) = y - 0.0125y = 0.9875y
Net Proceeds = 0.9875y - 1.01x
Answer:
k= -13
Step-by-step explanation:
-6k = -10 + 88
-6k = 78
k = -13
